We test the interaction between COVID-19 governments' interventions, COVID-19- induced uncertainty, and the volatility of sovereign bonds. Using a panel-quantile approach and a comprehensive dataset of 31 countries worldwide, we document that containment and closure policies tend to amplify...

We look into determinants (volatility, crises, sentiment and the U.S. ‘fear’ index) of herding using BRICS as our sample. Investors herd selectively to crises and herding is a short-lived phenomenon. Herding was highest during the global financial crisis (only China was affected). There was...

We build a parsimonious agent-based model under the adaptive market hypothesis (AMH), which can explain the formation of equilibrium prices and market efficiency dynamics. Our model combines heterogeneous interacting agents, switching behavior, and investor feedback on past realized returns,...

We investigate different designs of circuit breakers implemented on European trading venues and examine their effectiveness to manage excess volatility and to preserve liquidity. Specifically, we empirically analyze volatility and liquidity around volatility interruptions implemented on the...

We investigate the volatility impacts of the full commission deregulation in Japan in October 1999, and find that the deregulation overall tends to significantly increase price volatility in the Japanese equity market, using alternative model specifications and control variables. This finding...

This paper examines the impact of MIB30 Index Futures on the volatility of the Italian Stock Exchange. The results suggest that the onset of futures trading may have led to diminished daily volatility. They also suggest that the nature of the volatility itself has not changed between the...

This paper examines the price discovery and volatility spill-over relationship for Indian commodity markets. We cover twelve actively traded commodities including agriculture, metal and energy and four commodity indices. Price discovery is confirmed for eight commodities and three indices with a...

The paper examines empirically the impact of price limits and trading halts on stock market volatility. Circuit breakers are regulatory instruments aiming to reduce severe price volatility and provide markets with a cooling off period. However, the effectiveness of circuit breakers on the...

Volatility extensions in closing auctions are designed to improve the efficiency of the closing price. We hypothesize that the channel for the efficiency increase is that extensions improve market integrity and investor trust in the auction mechanism. We confirm that the introduction of a...
